There have been many scientist who have dedicated their work to DNA. Gregor Mendel started the study of genetics when he performed an experiment involving genetics in 1857. Frederich Meishcer was the first to observe DNA. The most famous scientists in the field of genetics are James Watson and Francis Crick. They are famously known for creating the double-helix model of DNA, and discovering that DNA is double stranded in the double-helix form. ("DNA History") Deoxyribonucleic acid, DNA, is the genetic makeup that is found within every cell of humans. DNA contains biological instructions. It contains instruction that are used to produce proteins. DNA makes you who you are. In the millions upon millions of cells in the human body, each cell contains the same exact DNA. DNA can be found in two places in a cell. A majority of the time the DNA is found in the nucleus of the cell. This type of DNA is called nuclear DNA. DNA can also be found in the mitochondria of a cell. This type of DNA is called mitochondrial DNA. All DNA located in the mitochondria is inherited from the female in reproduction. This is due to the fact that only the egg has the mitochondrial DNA. DNA is found within the chromosomes of the nucleus. DNA contains a person’s genes, and determines almost every aspect of that person’s life. ("What is DNA?") The information that is found in DNA is stored in the form of a code. The code of DNA consists of four chemical bases. The bases are Adenine, Guanine,
